Packing for an Alaska cruise trips people up because the weather refuses to sit still. One hour you're shivering in the 30s Fahrenheit on deck as the ship noses toward Glacier Bay or the Hubbard Glacier; a few hours later you're wandering Juneau, where summer days can nudge 80 degrees. The fix, according to seasoned cruisers, is simple: layers you can add and shed, plus serious waterproofing.
Rain is almost a given, especially in July and August when most ships sail the Inside Passage. Locals swear by waterproof boots — Xtratuf rubber boots are nicknamed "the Alaskan sneaker" — and a lightweight rain jacket will earn its keep. The good news is you don't need a specialist shopping spree. Fleece jackets, zip-off hiking pants and sturdy walking shoes you already own will cover most situations, and if you book an excursion like glacier dog-sledding or kayaking, the operator supplies the cold- and wet-weather gear anyway.
Evenings depend on your cruise line. Princess and Holland America mix casual nights with smart-casual ones, and Cunard passengers in particular still enjoy dressing up — think sport coats and the occasional gown on sailings longer than a week. If that's not your thing, casual buffet restaurants are always on offer, or skip the ship entirely when it stays late in port and hunt down king crab or wild salmon ashore, where Alaskans dress for comfort no matter how fancy the menu.
Beyond clothes, a few items make a real difference. Binoculars top the list — you'll want your own for spotting whales, bears and eagles, even if the ship has some to lend. Sunscreen sounds odd for Alaska, but the long summer sun reflecting off ice is brutal, and the state's 30-plus mosquito species make bug spray equally non-negotiable. Pack a dry bag to protect your phone or camera on water excursions, a portable charger for long excursion days, and snacks from home, since cruise lines rarely stock granola bars and trail mix. An eye mask helps too: the summer sun can rise before 4 a.m., and cabin blackout curtains aren't always up to the job.
Practical details matter as well. Bring more prescription medication than you think you need — Alaska's port towns are small and pharmacies may not stock uncommon prescriptions — and split it between carry-on and checked bags. Motion sickness remedies are worth having for the Gulf of Alaska crossing and the open-water approach to Sitka. Check your line's document rules, too: some Alaska sailings accept a passport card or birth certificate plus photo ID, others require a full passport. Keep printed and digital copies of everything.
One last stress-saver: most ships have laundry rooms or send-out service, so you can pack light — especially useful if you're tacking on a land tour before or after the sailing. And if you forget something, the port towns take US dollars and carry familiar brands. When in doubt, prioritise outdoor gear over formalwear. Source: The Points Guy.
